ArcGIS下的油田勘探资料管理方案

在长期的石油勘探工作中积累了包括地震、测井、地质以及其它非震地球物理方法等方面的大量资料。对这些与空间信息密切相关的资料进行数字化管理的理想方案是通过地理信息系统平台实现。油气勘探数据管理系统选用ArcGIS平台。用商业DBMS如oracle8作为数据库服务器，采用三层式C／S结构，用ESRI的Geodatabase模型和ArcSDE建立分布式勘探地理数据库。整个勘探地理数据库按专业或专题分为若干子库，每个子库都可以位于地理位置不同的专业数据服务器上，通过油田内部宽带网连接。制订勘探资料元数据标准，并根据元数据标准编制元数据同步程序和编辑器，实现油田勘探资料的规范化管理。

Oilfields' Prospecting Data Management Scheme on ArcGIS

A large quantity of data in seism, well--log, geology and other non--seismic geophysics, has been accumulated during long period of petroleum prospecting. An ideal scheme to efficiently manage this type of spatial--related data in digitization is realized through GIS platform. The petroleum prospecting data management system is based on ArcGIS. With three--tier C/S architecture, a business DBMS e.g. Oracle 8 acts as its database server, and the distributed prospecting database are built with ESRI's geodatabase model and ArcSDE. The whole prospecting geographic database can be divided into several sub--databases according to data's specialty or theme. Every sub--database is located on specialized database server that is distributed at different geographic position linking with inner wide--band network of the oilfield. A metadata standard is formulated for the exploring data, a metadata synchronizer and a metadata editor are provided for a standardized management of oilfield exploring data.
